Final answer:
A trademark application can cost between $225 and $400 per class and is initially valid for 10 years, but can be renewed indefinitely as long as the trademark is being actively used in commerce.
Step-by-step explanation:
A trademark application can cost between $225 and $400 per class, depending on the type of application and the services provided by the trademark attorney. The cost may vary depending on the country or region where the trademark is being registered. For example, in the United States, the cost to file a trademark application with the United States Patent and Trademark Office (USPTO) ranges from $225 to $400 per class. In addition to the filing fee, there may be other costs involved, such as attorney fees or search fees.
The validity of a trademark registration can vary depending on the country or region. In the United States, a trademark registration is initially valid for 10 years from the date of registration. However, the registration can be renewed indefinitely as long as the trademark is being actively used in commerce. To maintain the registration, the trademark owner must file a renewal application and pay the renewal fee every 10 years. In other countries, the validity of a trademark registration may vary, but it is generally valid for a period of 10 years and can be renewed indefinitely as long as the trademark is in use.
